How does a managed container service affect control vs vendor lock-in?

[Amelia.C]

I'm trying to decide if we should move our container orchestration to a managed service, but I'm worried about losing control over the underlying nodes and networking. The whole point of our shift was to avoid vendor lock-in, but now managing the control plane ourselves feels like a huge operational burden.

We moved to a managed control plane last quarter. The toil dropped a ton, upgrades were smoother, and monitoring became simpler. But we suddenly couldn't tweak CNI behavior or node taints the way we used to. Debugging issues meant pinging support instead of poking at kubelet flags. It felt like we traded granular control for predictability.

One realization: the promise of avoiding vendor lock-in shrinks when you lean on a managed service's networking features. We relied on a feature that only exists in that provider, and suddenly you’re shipping workloads that only talk to that network stack. It wasn’t plan A anymore.

We tried a hybrid approach, kept a tiny on prem or self managed cluster for sensitive workloads, but it turned into more dashboards and more synchronization work. The fear of the control plane drifting away wasn't fully gone.

Do you have a clear must have list for networking and control that would actually be broken by a managed control plane?
